Examples
The following example creates a DataTable with one DataColumn and ten DataRow objects. After deleting a DataRow, trying to return the removed row's current version causes a VersionNotFoundException exception being thrown.
private void DemonstrateVersionNotFoundException()
{
// Create a DataTable with one column.
DataTable table = new DataTable("NewTable");
DataColumn column = new DataColumn("NewColumn");
table.Columns.Add(column);
DataRow newRow;
for(int i = 0;i <10;i++)
{
newRow = table.NewRow();
newRow["NewColumn"] = i;
table.Rows.Add(newRow);
}
table.AcceptChanges();
try
{
Console.WriteLine("Trying...");
DataRow removedRow = table.Rows[9];
removedRow.Delete();
removedRow.AcceptChanges();
// Try to get the Current row version.
Console.WriteLine(removedRow[0,DataRowVersion.Current]);
}
catch(System.Data.VersionNotFoundException)
{
Console.WriteLine("Current version of row not found.");
}
}
Private Sub DemonstrateVersionNotFoundException()
' Create a DataTable with one column.
Dim table As New DataTable("NewTable")
Dim column As New DataColumn("NewColumn")
table.Columns.Add(column)
Dim newRow As DataRow
Dim i As Integer
For i = 0 To 9
newRow = table.NewRow()
newRow("NewColumn") = i
table.Rows.Add(newRow)
Next i
table.AcceptChanges()
Try
Console.WriteLine("Trying...")
Dim removedRow As DataRow = table.Rows(9)
removedRow.Delete()
removedRow.AcceptChanges()
' Try to get the Current row version.
Console.WriteLine(removedRow(0, DataRowVersion.Current))
Catch e As System.Data.VersionNotFoundException
Console.WriteLine("Current version of row not found.")
End Try
End Sub
